Nursing Elites

1. During an acute exacerbation of asthma, what is the nurse's first action for a client experiencing this condition?

• A. Administer a bronchodilator as prescribed.
• B. Check the client's oxygen saturation.
• C. Reassure the client and encourage deep breathing.
• D. Provide emotional support to reduce anxiety.

Correct answer: A

Rationale: The correct first action when managing an acute exacerbation of asthma is to administer a bronchodilator as prescribed. Bronchodilators help open the airways and improve breathing in individuals experiencing an asthma exacerbation. Checking oxygen saturation (Choice B) is important but not the first action. Reassuring the client and encouraging deep breathing (Choice C) can be beneficial but should come after administering the bronchodilator. Providing emotional support to reduce anxiety (Choice D) is important but is not the initial priority in managing an acute exacerbation of asthma.

2. The nurse is teaching a client with asthma to use a peak expiratory flow rate (PEFR) meter to manage asthma at home. The nurse knows the client understands the proper use of the meter when the client:

• A. Inhales as rapidly as possible when using the meter
• B. Records the highest of three readings
• C. Uses the meter after taking a bronchodilator
• D. Blows out forcefully into the meter after taking a deep breath

Correct answer: B

Rationale: The correct answer is B: 'Records the highest of three readings.' When using a peak expiratory flow rate (PEFR) meter, the client should record the highest of three readings to ensure an accurate measurement of their peak expiratory flow rate. Inhaling rapidly, using the meter after taking a bronchodilator, or blowing out forcefully into the meter after a deep breath are not correct techniques for using a PEFR meter and may lead to inaccurate results.

3. To prevent unnecessary hypoxia during suctioning of a tracheostomy, what must the nurse do?

• A. Apply suction for no more than 10 seconds
• B. Maintain sterile technique
• C. Lubricate 3 to 4 inches of the catheter tip
• D. Withdraw catheter in a circular motion

Correct answer: A

Rationale: The correct answer is to apply suction for no more than 10 seconds. Prolonged suctioning can lead to hypoxia, so it is essential to limit the suctioning time. Maintaining sterile technique (choice B) is important to prevent infections but is not directly related to preventing hypoxia during suctioning. Lubricating the catheter tip (choice C) helps with insertion but does not specifically address hypoxia prevention. Withdrawing the catheter in a circular motion (choice D) is not a standard practice during tracheostomy suctioning and does not help prevent hypoxia.

4. A client with deep vein thrombosis (DVT) is prescribed heparin therapy. What laboratory value should the nurse monitor?

• A. Monitor the client’s liver function tests.
• B. Monitor the client’s prothrombin time (PT).
• C. Monitor the client’s partial thromboplastin time (PTT).
• D. Monitor the client’s red blood cell count.

Correct answer: C

Rationale: The correct answer is C: Monitor the client’s partial thromboplastin time (PTT). During heparin therapy for DVT, it is essential to monitor the PTT to assess the effectiveness of the medication in preventing clot formation. Monitoring the PTT helps ensure that the client is within the therapeutic range for anticoagulation. Choices A, B, and D are incorrect because liver function tests, prothrombin time (PT), and red blood cell count are not specifically monitored to assess the effectiveness of heparin therapy in preventing clot formation.

5. Which medication should the nurse withhold if the client's serum potassium level is 6.2 mEq/L?

• A. Losartan
• B. Spironolactone
• C. Metoprolol
• D. Furosemide

Correct answer: B

Rationale: The correct answer is B: Spironolactone. Spironolactone is a potassium-sparing diuretic that can lead to hyperkalemia. With potassium levels already elevated at 6.2 mEq/L, withholding Spironolactone is essential to prevent further increase in potassium levels, which could result in dangerous cardiac arrhythmias. Losartan (Choice A) is an angiotensin receptor blocker and does not directly affect potassium levels. Metoprolol (Choice C) is a beta-blocker and also does not impact potassium levels significantly. Furosemide (Choice D) is a loop diuretic that can actually lower potassium levels, so it would not be the medication to withhold in this case.
